8th Grade Math Rotations

Front

What is a rotation in geometry?

Back

A rotation is a transformation that turns a figure around a fixed point, called the center of rotation, by a certain angle in a specific direction.

Front

What is the center of rotation?

Back

The center of rotation is the fixed point around which a figure is rotated.

Front

What does a 90° clockwise rotation look like?

Back

A 90° clockwise rotation turns a figure to the right, moving points in a circular path around the center of rotation.

Front

What is the result of rotating a point (x, y) 90° clockwise about the origin?

Back

The new coordinates will be (y, -x).

Front

What is the result of rotating a point (x, y) 90° counterclockwise about the origin?

Back

The new coordinates will be (-y, x).

Front

What happens to the coordinates of a point when it is rotated 180° about the origin?

Back

The new coordinates will be (-x, -y).

Front

How do you determine the angle of rotation for a figure?

Back

The angle of rotation is the measure of the turn from the original position to the new position, measured in degrees.

Front

What is the difference between clockwise and counterclockwise rotation?

Back

Clockwise rotation moves in the same direction as the hands of a clock, while counterclockwise rotation moves in the opposite direction.

Front

If triangle ABC is rotated 90° clockwise, what is the new position of point A if A is at (3, 2)?

Back

The new position of point A will be (2, -3).

Front

What is the angle of rotation for a full rotation?

Back

The angle of rotation for a full rotation is 360°.
